U.S. House Special Election

It is my understanding that this coming Tuesday will see the last Republican vs. Democrat contest before the November general election, which will be the first after this decade's redistricting. There are currently two other vacancies in the U.S. House, but they will not be decided until special elections which will correspond with those in November for the full terms.

I always predict every U.S. House race, so here goes:

Arizona:

8. Vacant upon the resignation of Gabrielle Giffords (D)- (McCain 52%)

Tossup (D)
